Exodus 12:44

“A servant who is born in your house or who is bought with your money shall surely be circumcised; thus shall My covenant be in your flesh for an everlasting covenant.

‘But if a priest buys a person as his property with his money, that one may eat of it, and those who are born in his house may eat of his food.

For a multitude of the people, even many from Ephraim and Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover otherwise than what was written. For Hezekiah prayed for them, saying, “May Yahweh, who is good, atone

when you brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in My sanctuary to profane it, even My house, when you brought near My food, the fat and the blood. So they made My covenant void—this in addition to all your abominations.

By faith he kept the Passover and the sprinkling of the blood, so that he who destroyed the firstborn would not touch them.
